Fractal structure silver particle-based flexible and stretchable conductor and preparation method thereof

Abstract

The invention relates to a preparation method of a fractal structure silver particle-based flexible and stretchable conductor. The preparation method is characterized in that the stretchable conductoris prepared from fractal structure silver particles as a conductive filler. The fractal structure silver particles have a special three-dimensional structure, so that interconnection is facilitated to form a conductive network; and the fractal structure silver particles are embedded into a polydimethylsiloxane (PDMS) surface, so that the stretchable conductor with excellent performance can be prepared. The method is simple in synthesis process of the fractal structure silver particles and has good repeatability. The flexible and stretchable conductor is prepared from the fractal structure silver particles as the conductive filler, and research on the stretchable conductor is expanded. The obtained conductor has the characteristics that the preparation process is relatively simple, the energy consumption is relatively low and the stability of the conductivity under a mechanical deformation condition is good; the conductor can be applied to industrial batch preparation and can be applied to flexible and stretchable electronic equipment; and the synthesis method is clean, environment-friendly and suitable for promotion and application.

Description

technical field [0001] The invention relates to a flexible and stretchable conductor based on fractal structured silver particles and a preparation method thereof. Background technique [0002] Electronic devices have become a necessity in people's daily life, and the appearance of flexible and stretchable functions further promotes people's life, which is one of the future trends of electronic devices. Flexible and stretchable electronic devices have been studied and gained much attention because conventional electronic devices are prone to failure under deformation conditions. As an important component of stretchable electronic devices, flexible and stretchable conductors are widely used in electronic devices such as flexible light-emitting devices, electronic sensors, flexible batteries, and electronic skins. Stretchable conductors are mainly composed of conductive fillers and elastic polymers, where the conductive fillers provide electrical conductivity and the elastome...
